Probably a very stupid idea to get lithium from a battery
Hey,
Straight to the point: we all know we can get lithium by taking out from an energizer battery, and we all know the problem with this is that the
lithium oxidizes really quickly..
So.... I was thinking: what if we were to extract the lithium from the battery UNDER mineral oil. As in filling a container with oil, dumping the
battery in and working under the oil to extract it in order to prevent oxidation?
A part of me tells me this is a very stupid idea, as any spark generated by the battery will be enough to cause the mineral oil to light up...
Obviously unpleasant
But another part of me thinks that maybe it won't light up? I believe I read that mineral oil requires quite a lot of heat to ignite...
Could this technique work? Opinions?

Depends on what mineral oil are you using. The heavier lubricant oils do not light up easily. Probably even diesel fuel will be somewhat spark
resistant, but nevertheless I would prefer heavy mineral oil just to be on the safe side.
Smells like ammonia....

Use baby oil.Make sure that it is mineral oil,otherwise,there will be a surprise.

a spark wont light up oil. it needs to be heated considerably to ignite by spark. you should get a nice piece of Li by this procedure.

The ease of doing this depends on the battery. Some old design lithium batteries had a solid plug of lithium which was easy to extract and get useful
lithium from. Most modern designs use lithium foil which is a pain. I think rayco were one of the "solid lithium" designs.
If you're not part of the solution, you're part of the precipitate.

If you are only looking for lithium ion, it is stupid idea.
If you are looking for lithium metal, good.
You can also extract it from stone or soil.
One kg soil has 10 - 20 mg Li.
Meaning that 10 kg soil has more than one Li-ion battery.
But only do that if you need other elements also.

Soil as a starting material sounds like a lot of hard work.

by keeping the battery under oil while extracting the Li foil there will be no sparks .
if the battery is shorted and starts to heat up the oil should still not ignite.
use a large amount of oil so you can work and extract the metal under the surface.
even with diesel (not the best healthy choice) it has to be heated . even an open flame wont ignite cold diesel.
the vapors are burning not the liquid with a hot (or warm) liquid, more vapors can mix with air until there is enough combustible vapors to reach the
lower limit of ignition .

You rightly claim that if you're looking for 'lithium ion' then using a lithium metal battery is 'stupid idea'.
Yet extracting lithium ions from soil is also 'stupid idea'. The extraction of lithium compounds from high quality ores is already hard enough, never
mind from generic 'soil'.

Although this method should work nicely to prevent oxidation, you've missed an important practical detail. Anyone who's ever opened a lithium battery
will know how strongly they are constructed; accessing the lithium is difficult, fiddly and frustrating in open air using two hands, let alone under
slippery oil.

there is an easy way with a pipe cutter... its fast and would easily be done under mineral oil as well...
there was a thread on that somewhere...

I've tried to open a Li battery with a pipe cutter and it wasn't easy. The pipe cutter tended to pinch in the end of the battery so that once the end
was taken off, the contents of the battery could not easily be pulled put.
Also the only way I could get a good grip on the battery was to put it in a vice, which is something you can't do while the battery is submerged in
oil. Perhaps some vice grips would work better.
One possible alternative to doing this in a big vat of oil is to just regularly dip the battery in oil as you take it apart. Mineral oil is moderately
viscous so you should get a persistent coating, and this method has the advantage that you don't need lots of oil and you can use big tools to help
you open the battery.
I have a feeling cutting lengthwise carefully with a dremel wheel could work well.

practice practice practice.... i can get Lithium out of 10 battery in less than 8 minutes... pipe cutter and needle nose thats it.

I use a hacksaw blade (carefully) since I have no pipe cutter. Once the cut is made in the casing then the rest is easy with pliers.
I think I will attempt the next extraction under oil. It should be a cleaner result.

Build you a boxglove in inert atmosphere, CO2, Argon,Nitrogen. Is apparatously and someone expensive but effective.

Definitely not nitrogen. Lithium can react with that, too.
Smells like ammonia....

Dremel on a flexible arm thing is working for me under oil.
I am using cutting discs attached to the flexi arm and cutting just under the oil, it splashes a bit of oil about but seems to be going ok.
Dont ask me, I only know enough to be dangerous

I don't have much of a use for lithium but I would recommend working the battery in a tray with raised edges, with only a cm or so of oil in it. I'm
sure tools would be easier to use.
